YESLER TERRACE :: Seattle, Washington

urban design case studies THE DEVONSHIRE QUARTER :: Sheffield, England The Quarter has seen a renaissance of life due to several dynamic mixed use, urban infill development projects.

Each project integrates with the existing neighborhood and reinforced the sense of place by further stitching the fabric of the existing community as an identifiable place. Each project contributes a mix of residential units, boutique shops, bars, restaurants and community uses.

HAMMARBY SJOSTAD :: Stockholm, Sweden This project exemplifies large scale urban design principles and vision that are the result of solid master planning and strong public leadership. It includes multiple sustainable elements, a diverse collection of neighborhoods, social housing and a thoughtful public realm system.

EMPIRE SQUARE :: London, England Integrated urban design, landscape and architectural thinking tranforms this irregular three acre block into a distinctive and memorable urban neighborhood. Although relatively small, Empire Square informs the potential for one of the high rise sectors of Yesler Terrace. Through thoughtful design, the affordable housing component is integrated and indistinguishable from market rate units.

GREENWICH MILLENNIUM VILLAGE :: London, England This project offers a mix of inspiring open spaces, pedestrian walkways and contemporary design. The architecture reflects contemporary sustainable practices with twenty percent of the dwelling units reserved for social housing which is indiscernible from market rate housing.

The Devonshire Quarter

Sheffield, England

The Devonshire Quarter is located in the center of Sheffield, England, in a traditionally industrial and residential neighborhood. After WWII the demolition of derelict buildings lead to a series of disjointed developments during the early 1980’s that created the opportunity to reinvent the district. Recent developments are mixed use and much more urban in nature. Housing components achieve densities of up to 180 dwelling units per acre. As a result, Devonshire Street is now known for its independent shops and variety of pubs and bars that have energized the Quarter as an alternative, hip urban village. The area has a population of over 1,000 and is expected to grow to more than 5,000. Significant public realm improvements strengthen the connection between the Quarter and the Sheffield city center.

Devonshire Quarter offers lessons of how infill development that provides a proper mix of open space and land uses combined with a range of public realm initiatives can create a vibrant urban neighborhood.

Hammarby Sjostad

Stockholm, Sweden

The urban design of Hammarby Sjostad is based on Stockholm city standards in terms of street width, block sizes, densities and land uses, thus integrating it with the city through familiarity of scale. The traditional city block structure combines with contemporary architectural styles that respond specifically to the waterside context and promote integrated sustainable technology.

At 18 dwelling units per acre, the gross density is relatively low. This is due in large part to the variety of open spaces, pedestrian connections, and sustainable features. The project has succeeded beyond expectations in attracting families with children and is a model for large scale sustainable development practices. Among the ample amenities provided for families are three schools, a preschool and nursery, a library, a sports center and children's play areas. A mix of specialty shops, bars, restaurants, and entertainment venues coupled with multiple public transit options maintain an urban character.

innovation Hammarby Sjostad Hammarby Sjostad integrates many creative and leading sustainable concepts in design and management. These notions will become the standards for the future: • Ground floor of all buildings is built as flexible space suitable for commercial, community or leisure use.

• Native reeds and rushes are preserved or have been rehabilitated at the waterfront.

• Tram and transit infrastructure is incorporated into design, and new bus routes and a free ferry across Hammarby Sjo have been added.

• Car share program includes more than 270 residents as members.

• From the outset, the project goal was to be twice as environmentally effective as typical new construction.

Success of achieving targets is monitored and shared through on information kiosks and community website.

• Sanitary sewage is cleaned and purified at a large sewage plant nearby. Heat produced through the purification process is recycled as natural gas at a district‐heating unit, providing an energy source for the neighborhood. Nutrients from sewage are recycled for use on nearby agricultural land.

• Storm water is naturally filtered onsite.

• Each apartment block has recycling facilities.

• Any combustible waste produced is recycled into heat energy for use in the apartments.

• Biodegradable waste is composted nearby.

• An environmental education center built at center of district to educate residents.
